Combustion reaction
Key: O2
O2 is normally in a chemical formula when you are used to burn anything, so basically, anything with O2 involves burning.

An experiment in a general chemistry laboratory calls for a 2.00 M solution of HCL. How many mL of 11.9 M HCL would be required
Annette [7]

<u>Answer:</u> The volume of concentrated solution required is 42 mL

<u>Explanation:</u>

To calculate the molarity of the diluted solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated solution

M_2\text{ and }V_2 are the molarity and volume of diluted solution

We are given:

M_1=11.9M\\V_1=?mL\\M_2=2.0M\\V_2=250mL

Putting values in above equation, we get:

11.9\times V_1=2.0\times 250\\\\V_1=42mL

Hence, the volume of concentrated solution required is 42 mL

What is potiential and kinetic engergy? pls someone answer my question
Afina-wow [57]

Answer:

Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.

Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
